Turn off materials while rendering?

Hi all,

this question may sound little weird :expressionless: but is it possible to turn off all materials at once to render preview?

I have one big scene completely textured, I thought it is done once for all, but now I would like to major redo lighting. It would be easier if I can make preview render without materials , just shade objects and lights and shadows as I can better see where all shadows go and judge intensity non influenced by diffuse colors.
Unfortunatelly I didnĀ“t figured out how to do this without need manualy unlinking materials one by one and than link again :expressionless:

If someone have idea I will be grateful for it.
Thanx

Ok, what you could do is make a full copy of the Scene.
Delete the material of the Active object.
Select all the other object (while still keeping the same active object)
Ctrl-L -> Materials.
